PROFILE

Ben Moon

Over the past year, Guilty Dolphin engineered privacy and experimentation features across DuckDuckGo’s privacy-configuration, Android, and content-scope-scripts repositories. They delivered domain-specific mitigations, adwall detection, and robust A/B testing infrastructure, using TypeScript, Kotlin, and JavaScript. Their work included configuration-driven rollouts, feature flag management, and cross-platform telemetry, enabling safer experimentation and rapid iteration. By implementing schema enhancements, automated triggers, and localization, they improved data quality and user experience. Guilty Dolphin’s approach emphasized traceable commits, regression-aware delivery, and risk mitigation, resulting in resilient, maintainable systems that support privacy controls, analytics, and reliable feature deployment across web and mobile platforms.

Dec 1, 2025

December 2025 monthly summary focusing on feature control and telemetry improvements across two key repos. The team reduced risk by halting ongoing experimental rollouts and expanding AppTP experiment controls, enabling more deliberate decision-making and cleaner feature surfaces. Key actions: - Privacy configuration repo: halted TDS Next Experiment rollouts (Android/iOS/macOS) and AppTP A/A experiment to reduce surface area while decisions are pending. Commits: 8203ccdd9b3c3e93387903afc62d8dc07d918807; 7f6f94025d98081d58d2539421a46137990f0e41. - Android repo: introduced new AppTP TDS experiment toggles and expanded metrics conversion window from 5 to 7 days to improve measurement and decision-making. Commit: c2815d2eeb23fd7a509d89ac5b4b45bdd3f05f29. Impact: - Reduced experimental risk surface across platforms, enabling focused decisions on feature rollouts. - Broadened telemetry coverage for AppTP TDS experiments, supporting more robust analysis and faster iteration cycles. - Demonstrated cross-repo collaboration and clear traceability from commits to business actions. Technologies/skills demonstrated: - Feature flag management and experiment toggling - Telemetry and metrics instrumentation (conversion window adjustments) - Cross-repo coordination, commit hygiene, and traceability - Risk mitigation through controlled feature rollouts

November 2025

Nov 1, 2025

2025-11 monthly summary for duckduckgo/privacy-configuration focusing on cross-platform experimentation and analytics. Key work included TDS Experiment 004 rollout across Android, iOS, and macOS with an initial 25% rollout and a subsequent transition to 100%, while deprecating version 003. This also involved updating control and treatment URLs to improve tracking and analysis. Additionally, App Tracker Protection (ATP) TDS Experiment 002 was enabled for Android (A/A) with URL updates to support robust analytics. No critical defects were reported; the efforts strengthen feature evaluation pipelines, privacy controls, and data quality.
